powerpc: move device_to_mask() to dma-mapping.h
Move device_to_mask() to dma-mapping.h because we need to use it from outside dma_64.c in a later patch. Signed-off-by: Mark Nelson <markn@au1.ibm.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
